LOCK.

Specification of Letters Patent. Patented Apr. 15, 1919.

Application filed November 15, 1915, Serial No. 61,634. Renewed September 20, 1918. Serial No. 254,988.

To all whom it may concern:

Be it known that we, GEORGE DANIEL and EDWARD G. LEWIS, citizens of the United States, residing atvMabscott, in the county of Raleigh and State of West Virginia, have invented new and useful Improvements in Locks, of which the following is a specification.

The invention relates to looks, and more particularly to the class of registering car door locks.

The primary object of the invention is' the provision of a lock of this character wherein on the unlocking of the door of a freight car the exact, time that the door is unlocked is recorded, and also the number of times of the unlocking thereof, thereby enabling a complete record to be had to entries to the car.

.Another object of the invention is the provision of a lock of this character wherein the chart for the recording of the time of the unlocking of the door is detachably mounted so that it can be removed from mined period of time, preferably the clockprovision of a lock of this character wherethe lock, and said chart is cooperative with clock mechanism for changing the position thereof throughout an interval of twenty four hours or more. in a given or determechanism being of the eight .dayv type,

thereby necessitating the winding of its spring at every eighth day period.

A further object of the invention is the in the construction thereofis novel in. form so as to assure the recording ofv the time of the unlocking thereof. for freeing the eflicient in its operation, strong, durable,

and inexpensive in manufactureand installation.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings Figure 1 is a fragmentary side elevation of the side of a car and its sliding door, showing the lock constructed in accordance with the invention applied.

Fig. 2 is an enlarged vertical longitudinal sectional view through the lock.

Fig. 3 is a fragmentary longitudinaltransverse sectional view showing the hasp engaged in the lock.

Fig. 4 is a fragmentary enlarged side elevation showing the indicator feed mechanism of the lock.

Fig. 5 is a fragmentary sectional view on the line 5 5 of Fig. 2. V

Fig. 6 is a sectional view on the line 66 of Fig. 2.

Fig. 7 is a detail view of the markers. S1m1lar reference characters indicate corresponding parts throughout the several views in the drawings. v

Referring to the drawings in detail, A

designates a portion of the side'of a rail-- way box car, and B a portion of the sliding door, which is of the ordinary well-known construction for closing the doorway in the side A of the car, as usual, and upon this side A is mounted the lock hereinafter fully described. r

The lock comprises a substantially rectangular shaped case 10, preferably made from metal, and issuitably fastened to the inner face of the side A, and within this case is arranged a latch bolt 11 pivotally mounted at 12 intermediate its ends, and provided at one endwith a hasp engaging shoulder 13, and at the other end withan upwardly curved extension 14 normally held adjacent to a keyhole 15 so as to be capable of being operated against by means of a key when inserted in the keyhole 15 and turned in one direction, as will be clearly understood by those familiar with the art to which this invention pertains.

Beneath the latch bolt 11 are stationary stops 16 and 17, which serve to limit the pivotal movement of the latch bolt, the latter being normally held in a certain predetermined position by means of a retractile spring 18, one end of which is connected to a lug 19 on one end of the latch bolt, while the other end of the said spring is connected to a fixed point 20 within the case.

The extension 14 is provided with a shoulder 21 which prevents the turning of the key in a reverse direction after it" has lifted the inner end of the latch bolt 11 for releasing the hasp engaging shoulder 13 for the unlocking of the lock.

One end of the lock case 10 is provided with an entrance opening 22' which is adapted to receive the pivoted end portion 23 of a hasp, said hasp having a base or fixed portion 24 which is secured to the outer face of the door B of the car in any suitable manner, the portion 23 being pivoted to an intermediate portion 25 which is also pivoted to the base portion 24 so that the said portion 23 can be positioned through the doorway to lie parallel with the inner face of the side A of'thecar for its engagement through the opening 22 in the case 10 withthe latch bolt 11 as shown when the door B .is moved to a closed position.

Adjacent to the outer end of the member 23 ofthe hasp is provided a notch 26 adapted to receive the shoulder 13 of the latch bolt, and the end of this latch bolt is beveled as shown art-27 so that when the end of the .hasp is thrust inward through the entrance 13 snaps into engagement with'the notch 26' inthe hasp, thereby locking the door.

To unlock the door a key is insertedthrough the keyhole 15 so as to cooperate with the extension 14 of the latch bolt, which V has the effect of movingthe shoulder 13 out of engagement in the notch 26 in the hasp,

permitting the latter to be again withdrawn through; the entrance slot 22 in the case.

the lock is operated there is provided a dial 28 on the. outer face of the side A of the car In order to register the number of times where it may be plainly and. easily observed,

' and in connection. with said dial there is employed an; indicator hand 29 mounted on an arbor 30 jiournaled in a suitable bearing in the side of the cars Mounted fast onthe arbor 30 is a ratchet wheel 31, while mounted loosely on said arbor isa disk 32 having pivotally mounted thereon apawl 33 adapted to anintermittentmovement .to the hand 29,

causing the same to travelaround the dial and registerwith the graduations thereon.

cqnnegted tot-he disk 32.js-a rod 34 which 7 V Spaced from the marking tip OI' Also engaging; with the teeth of; the ratchet wheel 31 is a retarding spring 36 -which preventsthe wheel 31- from Located wlthin the lock is an eight day winding clock mechanism of the ordinary well-known construction, which is held within the housing, the mainspring' of the said clock mechanism being wound through the medium of the winding arbor 38 which extends without the sidevA ofthe car so that a winding key can be attached thereto when the occasion requires the winding of the main spring of the clock, while upon the hand an bor 39 of the clock mechanism is fixeda circular shaped or disk-like chart 40 having printed or otherwise marked on its face graduations 41 indicative of the fractions of .each hour, and associated with these graduated marks are digits or numerals indicative of hour periods ranging numerically from one to twenty-four or more, the chart or dial 40 being detachably held on the arbor 39 to rotate therewith through the medium of a clip 42 carried by the said arbor so that on recording upon the dial or chart 40 the same the winding of the same upon a feed roller.

45, the said guide and feed rollers being journaled in a frame 46 supported upon a bearing 47 mounted interiorly of the case 10 p of thelock, and thisribbon 43 unwinds from a reel 48 which is detachably journaled on the bearing 47 below the feed roller 45. Supported at one side of theribbon 43 and journaled in an upright 49 is a horizontally disposed rocking shaft 50,. on which is mounted an arm 51 carrying a lateral ex-. tension 52 atright angles thereto, the same being disposed directly over the 'lower stretch of the ribbon43, and this extension has fixed thereto a depending marking tip or pin 53 which is adapted to work against the lower stretch of the ribbon 43 next to the dial or chart40 for themarking of the same when the door is opened in a manner presandcarriedby the extension 52 is a barrel expansion spring 57 held withinthefbarrel 54 and this tip or pin 56 is adapted towork against the-lower stretch. of the ribbon 43 next to'the dial or chart 40'for marking the presently described.

same when the door is closed, in a manner The shaft 50 has fixed thereto a crank 58 to which is pivotally connected an operating rod 59, the same being also pivoted at 60 to the latch 'bolt 11, so that on the movement of the latch bolt in one direction the shaft 50 will be rocked for the striking of the marking tips or pins upon the ribbon 43 in their respective order for making impressions upon the chart or dial 40, which is actuated by the clock mechanism within the housing 37, thereby recording the particular time the latch bolt is moved for the unlocking of the lock to free the door for the opening thereof and also the particular time the door is closed and locked. The shaft 50, at the end connected with the crank 58, has mounted thereon a ratchet dog 61 which engages the teeth of a ratchet wheel 62 fixed to the feed roller 45 so that on the movement of the shaft 50 the ribbon 43 will be fed intermitten-tly to prevent the tips or pins 53 and 56 from striking one point of the ribbon during the working of the look.

For a given period of time a complete record can be had upon the dial or chart L0 as to the number of'times the lock has been unlatched and latched so as to determine the entrance to the car and also as to the extent of time the door has remained open, as will be clearly apparent and also the exact time that the door has been closed.

In the operation of the lock, assuming that the door is normally open and on the closing thereof the latch bolt 11 trips the keeper or hasp which causes a slight rocking movement of the said bolt, thereby bringing the marking tip or pin 56 into a position to strike the ribbon 43 andthe making of an impression upon the dial or chart, thus in this manner indicating the time of the closing of the door. serted in the lock for the opening of the door the latch bolt 11 rocks to a greater degree than in engaging the hasp so that the marking tip or pin 53 is brought into engagement with the ribbon 43 and an impression is made upon the chart, thereby indicating the time of the opening of the door, it being seen that the marking tip or pin 56 will become retracted in the barrel 54 against the resistance of the spring 57 therein so as not to Now when a key is in-.
